The AC75: A Technological Masterpiece

At the heart of Luna Rossa’s 2024 campaign was the AC75, a revolutionary foiling monohull that has transformed competitive sailing. First introduced in the 2021 America’s Cup, the AC75 allows teams to achieve incredible speeds by “flying” above the water on foils, reducing drag and reaching speeds of 40 to 50 knots (over 90 km/h).

For those unfamiliar, foils are essentially underwater wings attached to the sides of the boat. As the boat picks up speed, these foils lift the hull out of the water, reducing drag from the water and allowing the boat to “fly” above the surface. This technology greatly increases speed and efficiency because the boat is no longer slowed down by the resistance of the water beneath it. (source)

The AC75 measures 23 meters in length and weighs around 7 tons. Powered by a combination of wind, cutting-edge materials, and hydraulic systems, these boats can reach speeds of over 50 knots (93 km/h) in the right conditions. The foils, which act like underwater wings, are the key to achieving these speeds. They lift the boat out of the water, allowing it to skim the surface at high speed, minimizing resistance and maximizing efficiency. (sources: #1, #2)

Luna Rossa’s AC75, designed with input from the best minds in naval architecture, uses foils with an asymmetric design, allowing the boat to fly efficiently in various wind conditions. The foils are constructed from carbon fiber, offering the perfect balance of strength and lightness, essential for both performance and durability. (source)

Behind the Technology: Luna Rossa’s Advanced Systems

The cutting-edge performance of Luna Rossa’s AC75 isn’t just a matter of design—it’s the result of a highly sophisticated combination of electronic, hydraulic, and human systems working in perfect harmony.

Foil Control and Flight Systems

At the core of Luna Rossa’s flight capabilities is the Foil Cant System (FCS), which controls the movement of the foils. This system, standardized across all AC75s, adjusts the angle of the foils based on wind conditions and the boat’s speed, allowing Luna Rossa to maintain balance while flying above the water. The FCS is connected to the Electronic Control Circuits (ECC), which manage the boat’s hydraulic systems. (sources: #1, #2)

Hydraulics refers to the systems that use pressurized fluids, like oil, to move parts of the boat. In Luna Rossa’s case, cyclors (cyclists who generate power by pedaling) pump oil into the system, powering the movements of the foils and sails. The cyclors’ power output ensures that the boat’s control systems can respond quickly to changes in wind or water conditions. Their efforts allow for precise movements), such as raising or lowering the foils, and adjusting the sails during maneuvers. (sources: #1, #2)

Instrumentation and Logging

Luna Rossa is equipped with an Instrumentation and Logging System (ILS) that gathers real-time data from onboard sensors, including GPS data, wind speed, and boat speed. This data is displayed on the crew’s information systems, helping the team make informed tactical decisions. To prevent any automated responses, the rules of the America’s Cup mandate a one-second delay between data collection and display .

This data is crucial because it informs the team of critical factors like wind direction, boat speed, and the positioning of competitors. However, to keep the race fair and ensure human skill remains the dominant factor, the rules impose a short delay between when the data is collected and when it is shown to the sailors (source)

Hydraulic and Manual Integration

A key feature of the AC75 is the integration of hydraulic and manual controls. While hydraulic systems power major components such as the foils and sails, the crew manually activates and manages these systems. Each maneuver, whether trimming the sails or adjusting the foils, requires precise coordination between the crew and the system controls, which is where Luna Rossa’s advanced training comes into play.

When watching an America’s Cup race, it’s easy to focus on the sleek, high-tech design of the boat, but the success of Luna Rossa Prada Pirelli also relies heavily on the crew and the specific roles they perform. Each member of the team plays a crucial part in managing both the speed and stability of the AC75. Here’s a breakdown of the key roles on Luna Rossa, explained in simple terms for non-experts.

The Roles Onboard the AC75

Helmsman (Timonieri)

The helmsman is the sailor who steers the boat. On Luna Rossa, this role is shared between Jimmy Spithill and Francesco Bruni, who alternate depending on the situation. The helmsman is responsible for the direction and speed of the boat, making constant adjustments to stay ahead of competitors. They use a wheel or tiller to guide the boat and must react quickly to changing conditions like wind direction, the position of other boats, and tactical maneuvers.

Trimmers

The trimmers manage the sails. On Luna Rossa, there are several trimmers, each responsible for different parts of the sail. The mainsail trimmer adjusts the main sail to capture as much wind as possible, optimizing speed. Other trimmers work on the jib (a smaller sail at the front) and the foils. They adjust the tension and position of the sails in real-time, helping to maximize the boat’s performance based on wind conditions. Trimming requires an understanding of aerodynamics, as the right tension can mean the difference between winning and losing.

Flight Controller

A key position on modern AC75 boats is the flight controller. The flight controller monitors and adjusts the foils, which are the underwater wings that lift the boat out of the water. The flight controller’s job is to maintain stability and keep the boat “flying” above the surface. They use a combination of hydraulic controls and real-time data to adjust the foils’ position, ensuring that the boat remains balanced even at high speeds and through maneuvers. This role is crucial for keeping the boat as efficient as possible, reducing drag from the water  .

Cyclors

The cyclors are the powerhouses of the AC75. Instead of traditional grinders (who use hand-powered winches), Luna Rossa uses cyclors, athletes who generate power by pedaling, similar to riding a stationary bike. Their leg power is used to drive the hydraulic systems that control the foils and sails. Luna Rossa’s cyclors, many of whom come from cycling and rowing backgrounds, provide the energy that allows the trimmers and flight controller to adjust the boat in real-time. Onboard, they can generate up to 2,000 watts of power, which is crucial for fast, responsive sailing  .

Tactician

The tactician is responsible for making strategic decisions during the race. On Luna Rossa, the tactician analyzes real-time data such as wind direction, the position of competing boats, and course layout to decide the best route. The tactician works closely with the helmsman to implement these strategies and adjust them as the race evolves. Their role is critical in high-pressure situations, as they must constantly predict the actions of competitors and adjust the boat’s course to maintain an advantage.

Support Crew

Though not always visible, the support crew plays a vital role before, during, and after the race. These team members include engineers, data analysts, and boat technicians. They ensure that the AC75 is in peak condition, monitoring the boat’s performance and making adjustments or repairs as needed. The support crew also analyzes data from the Instrumentation and Logging System (ILS), which provides real-time information about wind speed, boat speed, and the forces acting on the boat  .

How It All Comes Together

The AC75 is a complex boat, and without each of these roles working seamlessly together, the boat wouldn’t perform at its best. The helmsman navigates and steers, the trimmers maximize sail efficiency, the flight controller manages the foils to keep the boat balanced, the cyclors generate the hydraulic power needed to adjust everything, and the tactician ensures the best strategy is followed.

Each member of the crew must communicate effectively and perform their tasks with precision, all while racing at speeds of over 50 knots. This teamwork, combined with advanced technology and expert tactics, is what drives Luna Rossa in every race.
